The following two problems are resolved in this hotfix.
On a computer that is running Microsoft Windows XP Embedded in domain mode, you cannot modify public queue properties or computer properties if the queue is hosted on a Windows 2000-based computer. You receive the following error message:
"Invalid parameter was passed to a function."
If you delete a queue, and then immediately create a queue, you may receive the following error message:
"Queue is not registered in the DS."
This problem occurs because the Mqdscli.dll file is not installed on the computer that is running Windows XP Embedded.
This problem occurs because Microsoft Message Queuing uses the incorrect interface to modify objects in the Active Directory directory service.

If it is possible, you can copy the Mqdscli.dll file to the %windir%\system32 directory to work around this problem.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows XP Service Pack 2.
Message Queuing 3.0 can use Active Directory Service Interfaces (ADSI) to access Active Directory or the Directory Service RPC interface, depending on the version of Message Queuing that the client is running. The Windows XP Embedded Active Directory SLD file contains the Mqad.dll file, but it does not contain the Mqdscli.dll file. The Mqdscli.dll file is needed to use the Directory ServiceRPC interface. In domain mode, Message Queuing 3.0 uses the Directory Service RPC interface to the domain controller if the computer that owns the queue is running Windows 2000. This is done to enable "downlevel" notifications to the queue owner when the computer properties or the queue properties have changed because Message Queuing 2.0 can only accept "downlevel" notifications from a domain controller.
Important This hotfix makes the behavior more consistent across the Message Queuing Directory Service APIs. The Message Queuing Directory Service APIs are used to modify objects in the Directory Service over remote procedure calls. The APIs all now check to determine if the host is a downlevel computer and if it will call the Directory Service APIs. This does not mean that the application will not encounter problems because of replication delays. Internally, all Directory Service calls that query for objects always use ADSI.A well-written application must always assume that a Directory Service operation may not be immediately visible because of possible replication delays between domain controllers.
